Sewerage Services and Network

Sewerage Services and Network
The Moshi sewerage network was initially constructed and commissioned in 1962 with a total length of 19.5 Km sewer and a Trickling Filter as a wastewater treatment facility. This service was only available for the Central Business District. During that time, only 344 customers were connected to the services, which was under the management of Moshi Municipal Council.

The governments of Tanzania in collaboration with the World Bank, through Urban Sector Rehabilitation Project (USRP), expanded and rehabilitated the network and constructed wastewater treatment plant known as waste stabilization ponds.

This Sewer Network consists of sewer pipes of various types and sizes connected together by Manholes of different sizes. The sewer network has a total length of 44.084km, the sewer pipes are Cast Iron, uPVC, Clay and Concrete with sizes ranging from 100mm (4”) to 750mm (30”)
The service coverage is 12% of Moshi Municipal area, the population served by this network is 40% of the Municipal population.

Currently we have 2080 customers who are connected to this sewerage network.
